[Evaluation of modern epizootic activity of natural tularemia foci in Voronezh region using immune-serological and molecular-genetic study of main carriers of the disease].

Aim: Improvement of monitoring and prognosis of epidemic manifestations of natural foci of tularemia on the territory of Voronezh region using immune-serological and molecular-genetic study of main carriers of the disease.

Materials And Methods: 539 small mammals captured during summer period of 2011 in 4 districts of North-Eastern part of Voronezh region were studied. Animal organs were studied by serologic (search for Francisella tularensis antigens) and molecular-biologic (detection of F.

[Actual problems of hemorrhagic fever with renal syndrome].

From 2000 to 2011 85 600 cases of hemorrhagic fever with renal syndrome (HFRS) were registered in Russian Federation. Epidemically active foci of HFRS infection are located generally in temperate latitudes of the European part and the Far East. In the Far East regions whose fraction of all the HFRS disease cases in Russia is around 2%, the causative agents of the infection are Hantaan, Amur, Seoul hantaviruses, the natural reservoir for those are striped field mouse, Korean field mouse and brown rat.

[Monitoring of arthropods of epidemiological and sanitary importance in the city of Voronezh].

The paper analyzes the results of monitoring the number and species composition of arthropods, which are of epidemiological and sanitary important, in the city of Voronezh in 1998 to 2007. Many years' periodical observations have revealed the main places of breeding for blood sucking insects and ticks, their ecological features, including these under antropogenic stress. There is evidence for the changes in the species composition and the influence of some species on the recent epidemiological situation, which permits the approaches to and tactics of preventive measures to be corrected at the present budgetary stage oriented to outcome, with emphasis on the most significant sections of work.

[Epizootology of hemorrhagic fever with renal syndrome in the Central Chernozem Region].

A total of 5149 small mammals belonging to 16 species were collected from the Lipetsk, Voronezh, and Belgorod regions (40 administrative districts) in 2003-2004 and examined by ELISA and IFA to detect hantavirus antigen and antibodies in the lung tissues. Hantavirus circulation was revealed in 13 species, the highest hantavirus activity being detected in field (Apodemus agrarius) and small wood (A. (S) uralensis) mice (Dobrava-Belgrad virus), bank (Clethrionomis glareolus) (Puumala virus) and common (Microtus arvalis) (Tula virus) voles.
